Question

In GIS, what does the object-based model represent?

• A. Discrete features with identifiable boundaries and attributes
• B. 2D representation of 3D objects
• C. Randomly scattered features without any specific characteristics
• D. Continuous features with no boundaries

Hint:

Object-based GIS represents: \[ \boxed{ \text{Roads, Buildings, Rivers, Parcels} \rightarrow \text{Discrete Objects} } \] Each object has geometry and attribute information.

Answer 1

The Correct Option is A

Concept: The object-based GIS model represents real-world entities as discrete objects having well-defined boundaries and associated attributes. Examples include buildings, roads, lakes, and land parcels.

Step 1: Understand object-based representation. Each object consists of
• A definite geometric boundary.
• Attribute information.
• A unique identity.

Step 2: Choose the correct description. Hence, \[ \boxed{\text{Object-based models represent discrete features with identifiable boundaries and attributes}.} \] Therefore, the correct option is \[ \boxed{(A).} \]
